Abstract

Una composicion de formacion de fotoimagen, util como un fotorresistente para formar un tablero de circuito impreso, es tanto revelable en acuoso alcalino pero, después de la exposicion y revelado, es procesable en ambientes altamente alcalinos, tales como aditivo de baños de chapado y grabadores amoniacales. La composicion de formacion de fotoimagen comprende (A) entre alrededor de 25 y aproximadamente 75% en peso de un polímero aglutinante, (B) entre alrededor de 20 y aproximadamente 60% en peso de un material fotopolimerizable que es un monomero fotopolimerizable multifuncional u oligomero de cadena corta y, (C) entre alrededor de 2 y aproximadamente 20% en peso de un sistema químico fotoiniciador, los porcentajes en peso estando basados en el peso total de los componentes (A)-(C). La mejora es el uso en la composicion de formacion de fotoimagen de un polímero aglutinante (A) que es un copolímero de estireno/anhidro maleico en el que los residuos de anhídrido maleico son monoesterificados de entre alrededor de 50 y aproximadamente 65 por ciento molar de un alcohol de alquilo, arilo, cicloalquilo, alcarilo o arilalquilo que tiene un peso molecular mayor de 100, a entre alrededor de 15 y aproximadamente 50 porciento molar de un alcohol de C1-C3, y por los menos aproximadamente 80 por ciento molar total. El polímero tiene entre alrededor de 45 y aproximadamente 65 por ciento molar de residuos de estireno y entre alrededor de 35 y aproximadamente 55 por ciento molar de residuos de anhídrido maleico, un peso molecular promedio en peso de entre alrededor de 80,000 y aproximadamente 200,000, y un numero ácido de entre alrededor de 170 y aproximadamente 220.
